Public bug reported:

In our environment, the /var/log/neutron/server.log occasionally report
the following error: http://paste.openstack.org/show/751456/

I found it is resulted by https://review.opendev.org/#/c/236983/ and https://review.opendev.org/#/c/606383/. The two patches resolved they closed bug, but I think their solutions are not perfect.
They may result in the following issues:
1. Result in neutron-server raise ERROR log
2. If we encounter the case: https://bugs.launchpad.net/neutron/+bug/1795126, the old agent may create a redundant port. Because of the neutron-dhcp-agent may create a new port after it received DhcpPortInUse exception.

So, I think we should optimize these codes.
